Excitation voltage to the strain gauge sensor is supplied from the amplifier board. The amplifier derives all of its necessary power from a 14 to 33 Vdc supply. A range selector combined with span and zero potentiometers is available for calibration of the system.
Product Description of Terminal Enclosure - SCU 220:
The enclosure provides a simple field termination for vented gauge pressure transducers. An integrated micro filter assembly permits barometric reference while providing an effective barrier against ingress of water and dust.
A field-replaceable DRI-CAN desiccant module is attached to the internal face of the enclosure. This module attracts water vapor, condenses it, and retains it through surface absorption and capillary condensation.
The module is easily accessible once the cover is removed, and no tools are required for its removal and replacement. A moisture status indicator, which is clearly visible externally, alerts the user when replacement of the desiccant module is necessary.
